The PM Surya Ghar: Muft Bijli Yojana is a flagship initiative by the Government of India aimed at promoting the widespread adoption of rooftop solar in the residential sector. It offers attractive subsidies, simplified procedures, and financial benefits to encourage homeowners to generate their own electricity and reduce monthly bills. Our solar potential estimation tool is designed to support this initiative by helping users accurately assess the solar capacity of their rooftops, estimate monthly savings, and understand the financial viability of installing a rooftop solar system—while also factoring in central subsidies available under the scheme.

In support of national efforts, the Tamil Nadu Solar Energy Policy 2019 sets a target of 9,000 MW of solar energy capacity, with 40% expected to come from consumer-scale rooftop installations. The policy promotes net metering, streamlined approvals, and local participation in clean energy generation. By integrating the provisions of Tamil Nadu’s Solar Energy Policy 2019 into our estimation tool, users can access state-specific insights, such as net metering eligibility, expected returns, and local policy benefits. This ensures that both national and regional incentives are considered—making the tool a comprehensive guide for solar planning.
